Hello, what I'm trying to achieve is a setup where I have one frame of only assigned tanks and one other frame for everyone else except the tanks. I thought this custom layout below would do just that but it does not seem to be working. Am I doing something wrong or is this a bug? Addon version is 2.0.34-classic for Classic SoM 1.14.2

Unfortunatelly the problem relies on blizzard code so i cannot full fix the issue.
In version 2.0.44 I fixed the issue in the grid2 customheaders code, but this means you have to Disable Blizzard Unit Frames.
So to enable the fix you have to go to General/Layouts/General and Uncheck the "Use Blizzard Unit Frames" Option.
But keep in mind that if you disable blizzard unit frames, the unit frames changes cannot be updated while in combat, so if some player joins or leaves the raid while in combat (or players are moved between groups), grid2 cannot remove or add the players (until combat ends).

It works now! Thank you very much for the quick fix
